Multiple Antenna Communication With Time Reversal Mirror (MIMO-TRM) Pre- Processing

摘要

We have pioneered the study of time reversal (TR) pre-processing in radio wireless communication. Our results have shown that TR is beneficial for use in a rich scattering environment with many propagation paths, thus positioning the technique as a low complexity solution for high data rate communication via large delay spread channels. Methods to improve the performance of TR have been studied, and comparisons with other precoding schemes have been made. In particular, a TR system prototype has been designed, and is being built for carrying out future experiments.
